Filter for liquids capable of containing a gas

Abstract

A filter for liquids capable of containing a gas including a chamber for through-passage of a gas-charged liquid and which is subdivided into an upstream compartment and a downstream compartment by a filtering element, preferably in the form of a cylindrical strainer with a solid bottom, a liquid-supply pipeline opening into said upstream compartment, a liquid-outlet pipeline issuing from said downstream compartment, and an auxiliary conduit for exhaustion of gas directly communicating between said liquid-outlet pipeline and the upper part of said downstream compartment.

I claim: 
     
       1. A filter for liquids capable of containing a gas, said filter comprising a chamber for through-passage of a gas-charged liquid; a filtering element arranged in said chamber and subdividing said chamber into an upstream compartment and a downstream compartment; a liquid-supply pipeline opening into said upstream compartment; a liquid-outlet pipeline issuing from said downstream compartment, the working section of the outlet pipeline being smaller than the working section of the supply pipeline; and an auxiliary conduit for intake of gas directly communicating between said liquid-outlet pipeline and the upper part of said downstream compartment, said auxiliary conduit opening into said outlet pipeline through a constricted orifice functioning as a nozzle. 
     
     
       2. The filter as set forth in claim 1, in which said supply pipeline is located at the upper part of said chamber and at least the upper interior wall of the upstream compartment is concave in shape, the supply pipeline opening into the top of said concave interior wall. 
     
     
       3. The filter as set forth in claim 2, in which the filtering element consists of a cylindrical strainer having a solid bottom of convex shape with the convexity facing the downstream compartment. 
     
     
       4. The filter as set forth in claim 3, in which a magnet is arranged in the upstream compartment in the interior of the filtering element.
